Iowa Vehicle Registration Fees and Taxes for New Cars
New car registration in Iowa runs $125 to $400 or more each year. Fees depend on your vehicle's weight and list price. You also pay a one-time $10 new registration fee plus 5% tax on the purchase price.
Here's What You Need to Know
Iowa bases fees on a simple formula for most new passenger cars: $0.40 per 100 pounds of weight plus 1% of the list price. A typical new car weighs 3,000 pounds with a $18,500 list price. That calculates to $12 for weight + $185 for list price = $197 annual fee.
| Vehicle Weight Example | Weight Fee ($0.40/100 lbs) | List Price | List Price Fee (1%) | Total Annual Fee |
|---|---|---|---|---|
| 3,000 lbs | $12 | $18,500 | $185 | $197 |
| 4,000 lbs | $16 | $30,000 | $300 | $316 |
| 3,500 lbs | $14 | $40,000 | $400 | $414 |
One-time fees for new cars:
- New registration fee: $10 (increased in 2025)
- Title fee: $35
- Lien fee (if financed): $20
- 5% tax on purchase price
